If you came here after a search for the popular "Training for Service" book from Standard Publishing you may have expected this to be a book intended to train people for service as missionaries. Actually it is more of an informational guide to missions and training. It is still worth reading, however, especially in historical context.

Note the published date is listed as 1800. That is inaccurate, obviously. I have not read all of it yet, but skimming the book for clues I would say 1918 or possibly early 1919 would be likely.
